String Manipulation (Multi Column) fails with NullPointerException for missing values KNIME Analytics Platform

Hi, in reference to a bug report of mine I recognized the String Manipulation "Multi Column) fails with a NullPointerException for missing column values. It seems, though, it’s only for missing values BUT not, contrary to the initial bug report, caused by unspecific column types. From my perspective the String Manipulation (Multi Column) Node is heavily bugged and need to be fixed urgently. Here is the sample workflow showcasing the bug: https://hub.knime.com/mw/spaces/Public/latest/Bugs/S…
